Subject: Energetic electrons in connection with solar coronal jets

Flare-associated coronal EUV jets outline open magnetic field lines providing an escaping path to the interplanetary medium for particles accelerated during solar flares. Several studies have shown an observational link between coronal jets (observed in EUV or soft X-rays) and type III radio bursts, produced by escaping beams of energetic electrons, or in-situ energetic electron events. In a few events, coronal jets have also been associated with X-ray emitting energetic electrons during flares. However, the likelihood of the association of energetic electrons to coronal jets as well as the link between jet properties and electron properties has not been investigated on a large sample of events.

I will present a statistical study of the link between X-ray producing energetic electrons observed with RHESSI and the associated coronal EUV jets by looking at their relative timing, as well as their spatial and spectral characteristics. We found non-thermal X-ray emission in only 1/4 of our events, which were not necessarily the most energetic flares or jets. I will discuss the statistical distribution of properties of jets and associated flares in the context of jet modelling.
